BACKGROUND: Gemcitabine-Platinum doublet chemotherapy is the standard of care in patients with locally advanced inoperable and metastatic (LA/M) Gall bladder cancers (GBC). METHODS: Consecutive patients with LA/M GBC treated with Gemcitabine-Cisplatin (GC) or Gemcitabine-Oxaliplatin (GO) as first line palliative chemotherapy from January 2013 to June 2015 were retrospectively analysed. Patients who were able to continue chemotherapy beyond 6-8 cycles were separately compared to those who were potential candidates for this approach, but chose not to continue chemotherapy. RESULTS: A total of 396 patients received first line palliative chemotherapy during the period of analysis, 276 patients (69.6%) were unable to complete 6-8 cycles of chemotherapy, while 120 patients (30.4%) were potential candidates for continuing chemotherapy. Seventy patients (n=120; 58.3%) received a median of 4 cycles of continuation chemotherapy. Median overall survival (OS) for the entire cohort was 7.65 months [95% confidence interval (CI), -7.14 to 8.16], while median event free survival (EFS) was 4.53 months (95% CI, -4.23 to 4.83). Patients receiving continuation chemotherapy had a statistically improved median OS compared to all other patient cohorts, 14.88 months (95% CI, -12.48 to 17.27; P=0.005 on multivariate analysis). Burden/number of sites of metastases, receiving of continuation chemotherapy, fit and able to receive second line chemotherapy (CT2) were identified on multivariate analysis as prognostic factors for OS. CONCLUSIONS: OS in our study appeared lower than published literature, but a group of patients were identified whose survival could be prolonged by continuing chemotherapy. Easily available factors can predict prognosis of GBC undergoing first line palliative chemotherapy.
